Abstract

Un joint de charnière à volet divergent (22) pour une tuyère de vectorisation de poussée (10) est relié pivotant au volet convergeent (12) et le volet divergent (14) est relié pivotant à ce joint de charnière à volet (22). Un prolongement (48) du joint de charnière recouvre hermétiquement un évidement (50) ménagé dans le volet divergent (14).

Claims (4)

  1. Arrangement de charnière pour une tuyère convergente/divergente vectorisable à symétrie axiale, comprenant:
    un volet convergent variable (12) possédant une surface de volet convergent plane côté gaz;
    un joint étanche de charnière divergente (22) possédant une surface de joint étanche de charnière plane côté gaz;
    un volet divergent variable (14) possédant une surface de volet divergent plane côté gaz (56) coplanaire avec ladite surface de joint étanche de charnière plane côté gaz;
    un premier raccord pivotant (40) dont l'axe d'articulation (42) est parallèle à la fois à ladite surface de volet convergent plane côté gaz et à ladite surface de joint étanche de charnière plane côté gaz;
    ledit premier raccord pivotant (40) reliant ledit joint étanche de charnière divergente (22) et ledit volet convergent (12);
    et un second raccord pivotant (60) dont l'axe (62) est perpendiculaire à ladite surface de joint étanche de charnière côté gaz et reliant ledit joint étanche de charnière (22) et ledit volet divergent (14);
       caractérisé par le fait que:
    l'axe (42) dudit premier raccord pivotant et l'axe (62) dudit second raccord pivotant se coupent en formant un angle droit;
    la surface côté gaz dudit volet divergent présente une zone évidée (50) en position adjacente audit second raccord pivotant;
    et ledit joint étanche de charnière comporte un prolongement (48) chevauchant de manière étanche ladite zone évidée.
  2. Arrangement de charnière selon la revendication 1, comprenant également:
       le fait que ledit prolongement possède un bord arqué (52) dont le centre de courbure passe par ledit second raccord pivotant (60).
  3. Arrangement de charnière selon la revendication 2, comprenant également:
       le fait que la limite de ladite zone évidée (50) épouse la forme dudit bord arqué (52).
  4. Arrangement de charnière selon l'une quelconque des revendications 1 à 3, comprenant également:
    le fait que ledit premier raccord pivotant comprend deux broches coaxiales espacées (64), entre lesquelles est ménagé un espace;
    et le fait que ledit second raccord pivotant comprend une broche (58) logée dans ledit espace.
